I love Chicago. My favorite city in the USA.
I won't be there unfortunately,
There is no doubt, whatsoever, about Husker fans and traveling. Most, if not all, of our opponents raise ticket prices when NU comes to town. Check out Iowa's pricing for a prime example. I think Northwestern did so, I believe almost all our opponents do it. Some of the "major" schools may not, like OSU and PSU, but I wouldn't be surprised if they did. There are enough Husker fans willing to pay.
And the secondary markets, depending on small factors, can get crazy prices for certain seats and games.
I am uncertain whether this says good or bad things about us, but there is certainly a strong allegiance, and others recognize it as well.
